1 it known that I, HENRY WILLIAM ELLrooTr, 1 e city of Baltimore and State of Maryland, have int nted certain new and useful Improvements in Furna s; and I do hereby declare the following to be a ful and exact description thereof, reference being had is accompanying drawings and theletters of refermarked thereon.

igure 1 is the top viewofseginents bolted together wi l pipes connected.

igure 2 is a front elevation of segments, showing th notch a and cinder-run 0 together with inlet-pipe c r d outlet pipe d.

represents the coupling-pipe.

igure 3 is one of the side elevations showing the sc entine form. of pipe in its passage through those se ents with couplings e e.

igure 4is front elevation, with form of pipe for th t particular segment, with couplings e 0.

he nature of this invention consists in encircling th hearth or any part thereof, with a band or plates in segments or otherwise, of iron or any other 111 erial, cooled by water or air passed through pi s of serpentine or other form,by which means the or side of the hearth is kept sufficiently cool to resist I wear andtear inside, and the molten metal being fined to near the fusing-point, it remains so liquid is t an increased quantity of ore can be smelted, and t hearth itself kept a shape calculated to last lo ger and do its work better than any yet designed.

HENRY WILLIAM ELLIGOTT, OF. BALTIMORE, MARYLAND.

Letters Patent No. 110,639, dated January 3, 1871.

IMPROVEMENT IN PROTECTING THE HEARTHS OF FURNACES.

The Schedule referred to in these Letters Patent and making part of the same.

To enable others skilled in the artof manufiicturing iron to use this invention, I will proceed to describe the same, reference being had to the accompanying drawings and letters of reference marked thereon. 1

Fig. 1 represents a top view of the segments bolted together, and the pipes coupled, and inlet-pipe 0, outlet (Z, c c 6 being the coupling-pipe.

Fig. 2 is the front elevation, showinginlet-pipe c, outlet-pipe cl, notch a, and cinder-run I) together, with coupling-pipe c e c.

Fig. 3 shows one of the side segments and serpentine pipe in those particular segments, though not uecessaril any other form of cooling being equally good; but not so with fig. 4, this particular form of pipe being found best, not only for the protection of the notch a, but from the fact that thenearly-constant discharge of cinder through the aperture b causes that part of this segment to be liable to greater heat than any other segment, and, consequently, requires a little more protection.

\Vhat I claim for my invention, and desire to socure by Letters Patent, is-- Encircling the hearth of furnaces with water or air by means of pipes or otherwise, for the purposes and use expressed.
